As above really - DD is breastfed but tonight I had to go out for a few hours, DH was left with a ready made carton for DD just in case she became hungry. I fe her before I went out but she needed fed again, so DH gave her the carton. She only drank 50ml of it before falling asleep.
How long will the remaining formula keep in the fridge?
Would it last until Monday night or should I just bin it?
once heated it needs using within 2 hours so bin it. To save waste he could have poured some from the carton into the bottle and then the remainder in the carton could have been kept in the fridge for up to 24 hours.
